Benefits of technology

[0019]This plasma driven catalyst air purification apparatus is able to be operated in the ambient conditions, i.e. room temperature, atmospheric pressure and relative humidity. The removable gaseous pollutants include but are not limited to NOx, SO2, H2S, formaldehyde, NH3, volatile organic compounds (VOCs), organic odors, and airborne bacteria and virus. T

Problems solved by technology

These ionized components can deeply degrade the VOCs and other air pollutants into non-harmful products like CO2 and

Embodiment Construction

[0027]In the following description, a plurality of air purification apparatuses and systems are set forth as preferred examples. It will be apparent to those skilled in the art that modifications, including additions and / or substitutions, may be made without departing from the scope and spirit of the invention. Specific details may be omitted so as not to obscure the invention; however, the disclosure is written to enable one skilled in the art to practice the teachings herein without undue experimentation.

[0028]The plasma driven catalyst disinfecting and purifying apparatus in this invention can remove air pollutants and improve indoor air quality effectively and efficiently. This apparatus comprises a pre-filter, an electric fan, and a plasma reactor with catalyst inside. The plasma reactor is based on dielectric barrier discharge (DBD) plasma, which comprises two parallel spaced electrodes, and one or two dielectric barriers. The electrode is made of electrically conductive mater...

Abstract

The present invention relates to a novel plasma driven catalyst apparatus for disinfecting and purifying air. The apparatus has a synergistically favorable effect from plasma and catalyst on high disinfecting and purifying efficiency and efficacy, low by-product formation, and low energy consumption. The plasma combined with catalyst enhances the production of new active species, increases the oxidizing power of the plasma discharge, as well as activate the catalyst that additionally contributes towards the disinfection and purification process and the elimination of toxic by-products.
